rivt is an extensible, open source Python tool for writing and organizing engineering documents. It publishes a rivt file as a calculated and formatted text, HTML or PDF document (doc) file. A rivt file is a Python file (.py) that imports the rivtlib Python package and includes rivt markup.
A rivt report is a linked compilation of multiple rivt docs. This site is an example of an HTML rivt report.
